The Classification Of Plants - Annuals, Biennials and.
Using the tree for classification. Biologists use phylogenetic trees for many purposes, including: Testing hypotheses about evolution; Learning about the characteristics of extinct species and ancestral lineages; Classifying organisms; Using phylogenies as a basis for classification is a relatively new development in biology. Most of us are accustomed to the Linnaean system of classification.
Classification of Fungi. Division Zygomycota. Members of the division Zygomycota are known aszygomycetes. Zygomycetes produce sexual spores known as zygospores (Figure 1), as well as asexual sporangiospores. Figure 1. Sexual reproduction in the mold Rhizopus stolonifer. Plus and minus mycelia produce sexually opposite hyphae that fuse and give rise to zygospores, which germinate to form new.
Sphenophyllum, genus of extinct plants that lived from the end of the Devonian Period to the beginning of the Triassic Period (about 360 to 251 million years ago); it is most commonly reconstructed as a shrub or a creeping vine. Sphenophyllum had a strong node-internode architecture, which has led.
Classification of Nematodes. Nematodes are classified into the following classes: Phasmidia or Secernentea. These are mostly parasitic. Caudal glands are absent. Unicellular, pouch-like sense organs called plasmids are present. The excretory system has paired lateral canals. Eg., Ascaris, Enterobius. The class Phasmidia is divided into the following orders: Rhabditida. They have smooth and.
